Studying the adsorption of polymers and biomolecules on surfaces using enhanced sampling methods

We discuss how to use Wang-Landau simulations in an efficient manner to investigate the statistical mechanics of individual lattice polymers and peptides adsorbed at a planar surface. For nearest neighbor interactions, we show that a single Wang-Landau simulation, recording the density of states as a function of numbers of internal contacts and of surface beads, is sufficient to give a full description of the phase behavior of both adsorbed and desorbed states of single molecules. It is not necessary to introduce a second confining wall. Moreover, moves are never rejected due to overlap with the surface. The proposed “wall-free” method has already been applied to homo-polymers and hetero-polymers (lattice peptides using the HP model) on a uniform surface, and on regularly patterned surfaces. We give here a specific example to indicate how the relative adsorption strengths of a given peptide on different surfaces may be calculated

Monarchs in Love and Other Stories

Monarchs in Love and Other Stories is a collection of nine short stories. These stories are structurally and tonally heterogeneous, and it is this heterogeneity of form that emerges as the collection\u27s central concern. Present are stories which borrow other forms\u27 organizational conceits (the almanac entries of Excerpts from the Dwarf-Monger\u27s Handbook ), stories which arrange themselves around arbitrary organizational conceits (the order of the letters of the alphabet in 26 Characters ), and stories which employ radically traditional formal models ( Blind Boy and Mammoth. ) Present are stories narrated in the first-person point-of-view ( For a Walk, Harem Girls ), stories narrated in the second-person point-of-view ( Excerpts from the Dwarf-Monger\u27s Handbook, ), stories narrated in the third-person point of view ( Air, Elegy ), and stories which develop forms that utilize more than one style of point-of-view narration (second-person-singular and third-person-plural perspectives in Monarchs in Love. ) Present are works of magical realism ( In the Walrus Colony ), historical fantasy ( Excerpts from the Dwarf-Monger\u27s Handbook ), historical realism ( Air, Elegy ), and contemporary realism ( In the Palace of the Moon Sultan, For a Walk ). In short, Monarchs in Love and Other Stories attempts to explore as fully as possible the short story\u27s spectrum of form. As a collection, it hopes to make a virtue of its range

Accommodation of haptic learning style in traditional learning environments

2011 Spring.Includes bibliographical references.This case study intended to help teachers reach their audiences more inclusively. It determined if and how haptic learners, who preferred learning through touch, feeling, doing, and/or sensing; were being accommodated in college classrooms. Three professors were observed for in-class accommodations of haptic learners. Observations accounted teaching methods that were used to accommodate haptic learners. Data included determining learning styles of the students and professors via the Learning and Interpreting Modality Instrument (LIMI) to ascertain haptic volume. Also each professor's teaching preferences and philosophy was determined by the Principles of Adult Learning Scale (PALS) and the Philosophy of Adult Education Inventory (PAEI). The results of the instruments were analyzed to see if their preferences and philosophies affected their choice to accommodate haptic learners in their classrooms. Student Course Surveys were analyzed to see if students felt positive or negative towards their professor. The results lead to the discovery of if and how haptic learners were accommodated in these case studies. At minimum, 42% of each class's students were dominantly haptic learners. All professors effectively accommodated haptic learners as was determined by in-class observations and their Student Course Surveys. The professors used group work, repetition and active review, holding classes in non-traditional classroom settings, and collected student feedback as methods to accommodate the haptic learners. Each professor resided in the PALS learner-centered paradigm. Each showed strength in the secondary PALS categories of climate building and flexibility for personal development. The professors scored two dominant philosophies in their PAEI, and all registering Progressive Adult Education as a dominant teaching philosophy. Two of the three professors were dominantly haptic according to the LIMI, with the third professor as a dominantly visual learner; however he scored as a strong haptic learner. In all cases, the students were pleased with the professors and their courses, which insinuated they felt accommodated within the courses. Practitioner recommendations were made such as using the professor's examples to set a tone for those who wish to accommodate all learning styles by accommodating haptic learners, which in turn accommodate all learning styles inclusively

Surveilled

Debord\u27s Society the Spectacle and Delouze’s Deleuze\u27s Society of Control both imagine a dystopian future for humanity in a world governed by excessive self-advertisement and mass surveillance. This thesis begins with the observation that, sadly, their two visions have become a reality. Current technologies log our movements through GPS satellite data, and photographs taken by closed-circuit security cameras, or by passers-by on a public street, are constantly cross-checked against databanks of previously-compiled biometric profiles. Every movement and transaction is digitized and recorded, accessible to ever-widening networks of information exchange and surveillance. These data-networks are altering the manner by which people navigate through public space. People’s “right to the city” (citation), as well as the right to solitude, discretion, and clandestineness, are being eroded and fundamentally transformed. My site is the Parc de la Villette competition — reimagined to address the struggles and questions of a 21st century society. I propose a landscape constituted from overlapping anti-surveillance programatic strategies - audio, boundary, visual, masking, density, and path. Each program acts through a gradient of intensity [eg - from voices amplified and sound dropped to different specific points to zones of complete silence]. The goal of these surveillance-interrupting programs, and the sometimes surveillance intensifying ones, is to activate a new front in the struggle for human dignity and liberty. This new parc-de-la-villette will reconstitute and defend the social and political necessity for ‘privacy’ in the 21st century urban datascape

Review of Wyoming Biographies

Wyoming Biographies is a biographical dictionary (with a chatty introduction chronicling the settlement of Wyoming) that compiles in alphabetical order life sketches of approximately 265 pioneer citizens. Lawrence M. Woods has collated information from a variety of sources, drawing on contemporary subscription biographies, on more recently written histories, on biographies and memoirs of individuals, on reference works, and on miscellaneous materials (personal conversations and letters, materials in the Wyoming Historical Society collection, etc.). The content of entries varies, but most list the subject\u27s date and place of birth, date of migration to Wyoming, occupation, and government offices

Fact Sheet: Carbon Cycling in Southwestern Forests: Reservoirs, Fluxes, and the Effects of Fire and Management

Forest death from extreme drought and wildfires are reducing regional carbon reservoirs and overall forest sequestration capacity. At the same time, land use practices and development have increased the vulnerabil- ity of some forests during extreme droughts. The intent of this fact sheet is to explain the basics of the car- bon cycle in southwestern forests. It also summarizes how carbon cycling patterns are most likely to change in the coming years to decades in the Southwest

Working Paper 35: Carbon Cycling in Southwestern Forests: Reservoirs, Fluxes, and the Effects of Fire and Management

Forests play a key role in regulating the carbon cycle of the Earth system. Understanding carbon storage in forest ecosystems has become increasingly important as human activities release more carbon dioxide (CO2) into the Earth’s atmosphere. The intent of this working paper is to explain the basics of the carbon cycle detailing how much carbon moves through vegetation, water, and soils over time. The paper also summarizes where current science suggests that carbon cycling patterns are most likely to change in the coming years to decades, and how management can influence these changes. Water (H2O) and atmospheric gases, particularly carbon dioxide, interact with living things, soils and rock to regulate natural habitats and sustain ecosystems (NRC 2001). The capacity of landscapes to transfer (“flux”) and store (“sequester”) elemental carbon has a direct effect on atmospheric concentrations of CO2 with further feedbacks on the water and nitrogen cycles. In the literature, carbon contained in vegetation and soils is typically referred to as “reservoirs” or “pools” (Post et al. 1990, Schimel 1995, Cole et al. 2007)

Selecting an Air-Cure Tobacco Housing and Curing Facility

Once or twice in a lifetime the average tobacco producer faces the decision of what tobacco housing and curing facility he needs to build. For some, this may be to replace a barn that has burned or blown down. For others, the need may arise from an expansion of production by farm acquisition or lease-in of extra poundage. In all cases, it is important to build the most suitable facility for present and projected production methods. With labor becoming more costly and scarce, labor-saving features are a must Rising material and construction costs continue to increase the initial investment costs past previous levels
